After nearly two years on pause, we'd like to announce that we've given up on plans to continue production of the EEZ H24005. But we have not been on holiday! As some of you who contacted us already know, we've spent many hours trying to push the H24005 concept to the next level by addressing known issues and adding new features. From this effort was born EEZ Bench Box 3 (BB3)!
The BB3 campaign will feature early-bird pricing. Subscribe now to make sure you are notified when it launches!
BB3 addresses the following issues that we identified in the H24005:
|Feature||EEZ BB3||EEZ H24005|
|Backplane for Peripheral Modules||Yes||No|
|Max. Number of Modules / Power Outputs (Channels)||3 / 6||2 / 2|
|MCU Module||STM32F7 MCU Board||Arduino Shield r5B12|
|Power Module||DCP405 power module or DCM220 dual power module||Power Board r5B12|
|OVP (Over-Voltage Protection)||HW, fused (DCP405 only) / SW||SW|
|Reverse Power Output Protection||High power diode, fused (DCP405 only)||TVS, not fused|
|No. of Power Relays for Output Couplings||4 (Series, parallel, and split rail for first two modules; ground coupling for all modules)||2 (Outputs in series and parallel)|
|Flash Memory||2 MB||512 KB|
|Modules with On-Board EEPROM (for storing module specific params)||Yes||No|
|Rotary Encoder||Yes (Ø31 mm knob)||Yes (Ø16 mm knob)|
|User Defined Switch||Yes||No|
|Power Module Communication||Dedicated SPI||Shared SPI|
|Memory Card||MicroSD (accessible from the front panel)||SD (on the back of the TFT display)|
|Dedicated Fan Controller||Yes, up to 2 fans||No|
|Fan||Ø80 mm, 3- or 4-wire||Ø60 mm, 3-wire|
|Programmable Output Lists||Yes, low jitter||Yes|
|AC Input Range||Full range (115 / 230 V)||115 / 230 V (manually switchable)|
|Dimensions||290 (W) x 123 (H) x 240 (D) mm||290 (W) x 84 (H) x 238 (D) mm|
BB3's modularity is further enhanced by the DIB (DIY Instrumentation Bus) specification, which will allow us to offer additional categories of Testing and Measurement (T&M) modules in the future. To begin with, the upcoming BB3 campaign will give you the option to choose between three different DIB compliant DC power modules. That's up to six channels in a single box! Finally, we remain committed to a fully open source design, so all of our project files are available (and will be kept up-to-date) on our GitHub repository.
Thank you once again for all of your support and patience. We look forward to seeing you over on the BB3 campaign page very soon!
